Uber takes on de Blasio

The ride-booking service Uber's app has a new feature -- and it's very critical of Mayor Bill de Blasio.  Riders can now choose "de Blasio's Uber." It purports to show would what happen if a plan to cap the number of Uber cars on New York's streets is adopted.  David Plouffe from Uber said Thursday that the cap could cause "wait times in Manhattan to skyrocket."
